SPECIFICATION forming part of Letters Patent No. 570,617, dated November3, 1896.

Application filed October 22, 1894;. Serial No. 526,656. (No model.)

To a/ZZ whom it may concern:

Be it known that I, LEONA A. STOUGH, a

citizen of the United States, residing at Durango, county of La Plata,and State of Colorado, have invented a new and useful Pencil- Sharpener,of which the following is a specification.

The invention relates to improvements in pencil-Sharpeners.

The object of the present invention is to provide a combinedpencil-Sharpener and paper-weight adapted to be placed on a desk orother suitable support and capable of rapidly sharpeninga pencil and ofcollecting the shavings and preventing the accumulation of the same onthe desk or other support.

The invention consists in the construction and novel combination andarrangement of parts, hereinafter fully described, illustrated in thedrawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of a pencil-Sharpenerconstructed in accordance with this invention. Fig. 2 is a vert-icalsectional view of the same.

Like numerals of reference designate corresponding parts in both theiigures of the drawings.

l designates a base from which rises a centrally-arran ged screw 2,having a spiral groove 3, and receiving a nut 4 of avertically-reciprocating rotary pencil-holder 5. The pencilholder 5consists of a head 6 and a tubular shank 7 ,carrying the nut 4 at itslower end,and

adapted, when the holder is depressed, to receive the screw 2. The headis provided with a conical cavity 8 for the reception of the end ofapencil, and it is open at one sidefor the discharge of shavings, and ithas mounted on it at the opening an inclined blade 9. The blade 9 isprovided with an inner cutting-edge, and is adjustable by any suitablemeans, preferably slots 10 and screwsll, and it is capable of beingreadily detached for grinding or otherwise sharpening. As-thepencil-holder is forced downward, the screw causes it to rotate, thepencil being held stationary by the operator, and the knife is thuscarried around the pencil and effects a sharpening of the latter. Afterthe holder has been depressed it is raised automatically by a coiledspring l2, disposed on the screw and interposed between the base and thelower face of the nut. The screw is preferably provided with a grooveand the nut has a thread 13 but the construction may be reversed, ifdesired.

In order to collect the shavings and prevent them from becomingscattered over a desk or other support, a substantially cylindricalreceptacle 14: is employed and is mounted on the base and surrounds thescrew and the lower portion of the pencil-holder, and it is providedwith a central tubular portion 15, which forms a casing for the screwand the nut and which prevents any shavings or pencil dust accumulatingon the screw and clogging the device. The central tubular portion 15 isprovided at its top with an inwardly-extendin g horizontal ange 16,which forms a stop for the screw to limit the upward movement of thepencilholder. The device may be readily inverted to discharge thecontents of the receptacle.

It will be seen that the combined pencil- Sharpener and paper-weight isexceedingly simple and inexpensive in construction, that it is capableof rapidly sharpening a pencil, and that -it is adapted to collect theshavings, dust, and the like and will prevent the same from becomingscattered over a desk or other support.

Changes in the form, proportion, and minor details of construction maybe resorted to without departing from the principle or sacrificing anyadvantages of the invention.

l. In a pencil-Sharpener, the combination of a screw, a rotary verticalmovable pencilholder provided with a nut engaging the screw, a blademounted on the pencil-holder and arranged to discharge pencil shavingsexteriorly of the holder, and a receptacle receiving the screw, open atits top and adapted to receive such shavings, substantially asdescribed.

2. A pencil-Sharpener comprising a base, a screw mounted on the base, apencil-holder having a tubular shank and provided with a nut engagingthe screw and adapted to be rotated by the same, a blade carried by thepencil-holder, a spring for raising the pencilholder, and a receptaclemounted on the base and provided with a central tubular portionreceiving the screw and nut and forming a casing for the same,substantially as described.
